FSR402 Round Force Sensor

Arduino Code

//Visit web site " www.ekostra.com"
const int fsrPin = A0; // Analog pin where the FSR is connected
int fsrValue = 0;     // Variable to store the raw sensor value
float voltage = 0.0;  // Variable to store the voltage value

void setup() {
  Serial.begin(9600); // Initialize serial communication at 9600 baud rate
}

void loop() {
  fsrValue = analogRead(fsrPin); // Read the raw sensor value
  voltage = fsrValue * (5.0 / 1023.0); // Convert the reading to voltage

  Serial.print("FSR Value: ");
  Serial.print(fsrValue);
  Serial.print(" | Voltage: ");
  Serial.print(voltage);
  Serial.println(" V");

  delay(500); // Delay for 500 milliseconds before the next reading
}
